From Copstead and Banasik, 2000.cellular edema edema caused by the entry of water into the cells, causing them to swell.
This may occur because of decreased osmolality of the fluid surrounding the cells, as in hypotonic fluid overload, or increased osmolality of the intracellular fluid, as in conditions that decrease the activity of the sodium pump of the cell membrane, allowing the concentration of sodium ions within the cell to increase.cerebral edema swelling of the brain caused by the accumulation of fluid in the brain substance.
The disease is caused by the opportunistic proliferation of specific serotypes of Escherichia coli in an intestinal environment brought about by a change to a diet more dense in carbohydrates.
These have pilus attachment antigens that allow attachment of the organism to the small intestines and produce a verotoxin (VT2e) which produces an increase in vascular permeability in the target vessels in the CNS with resultant neurological disease.
